Splicing factors including cancer promoters (CLK2 [37], ELAVL1 [38], HNRNPA2B1 [14], HNRNPH1 [39], PTBP1 [13, 15, 40], SNRPB [41], SRSF1, SRSF2, SRSF3, SRSF7, SRSF9, SRSF10) and cancer suppressors (CELF2, MBLN2, QKI, RBFOX2 [42], RBM4, RBM5, RBM6, RBM10 [43], RBM11 [44], SRSF5) were applied to further correlation analysis. Here, QKI is linked to cancer.
